Genes affected

UMODL1 (HGNC:12560): (uromodulin like 1) Predicted to be an extracellular matrix structural constituent. Predicted to be involved in neutrophil migration. Predicted to act upstream of or within several processes, including adipose tissue development; cellular response to gonadotropin-releasing hormone; and regulation of ovarian follicle development. Predicted to be located in cytoplasm and external side of plasma membrane. Predicted to be integral component of membrane. Predicted to be active in apical plasma membrane; cell surface; and extracellular space. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification
